In a prosecution for robbery the defendants introduced evidence as to an alibi and requested a charge which contained the proposition that the evidence on this point had merely to raise a reasonable doubt as to their presence at the scene of the crime to entitle them to an acquittal. The court refused this request, but had previously instructed the jury that the burden rested with the state to prove the guilt of the. defendants beyond a reasonable doubt. Held, that it was reversible error to refuse the charge requested. People v. Vasquez (Cal. App. r928) 26g Pac. 549.
